EXTENSIBLE BED.

Specification of Letters Patent. Patented J une 23, 1914,

Application filed April 18, 1914. Serial No. 832,972;

To all whom it may concern Be it known that I, ANDY ToMKo, a subject ofthe King of Hungary, residing at Pittsburgh, in the county of Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovements in Extensible Beds, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to extensible beds and has for its object toprovide a bed of such class, in a manner as hereinafter set forth,capable of being conveniently extended when occasion so requires, andfoldable in a compact manner when not in use.

Further objects of the invention are to provide an extension bed whichis simple in its construction and arrangement, strong, durable,eificient and convenient in its use, readily set up and comparativelyinexpensive to manufacture.

\Vith the foregoing and other objects in View, the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more fully described and illustrated in the accompanyingdrawings, wherein is shown an embodiment of the invention, but it is tobe understood that changes, variations and modifications can be resortedto which come within the scope of the claim hereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views :Figure 1 is a side elevation of thebed when closed; Fig. 2 is a top plan view of the bed when closed; Fig.3 is an end view, partly in section, with the bed in closed position;Fig. 4c is a detail, broken away, illustrating the position of themattress support of the shiftable section when the bed is closed; Fig. 5is a top plan View of the bed when extended; Fig. 6 is an end view ofthe bed extended; and Fig. 7 is a detail, broken away, illustrating theposition of the mattress support when the bed is extended.

An extensible bed in accordance With this invention, includes astationary and a shiftable section, and the former includes a head piece8 and a foot piece 9. The head piece 8 is of greater height than thefoot piece 9, and with such exception, the head piece 8 is constructedsimilar to the foot piece 9, and the description of one applies to theother.

The foot piece and head piece each consist of a pair of posts 10-11connected together at their tops by a bridge member 12. The post 10 is.connected to the post 11 through the medium of horizontallyextendinghollow tubular members 12, 13 and 14, and one end of each ofsaid tubular members is attached to a four-way coupling 15 carried bythe post 10, and the other end of each of the said tubular members isconnected to a T-coupling 16, carried by the post 11. Attached to theposts 10, between the lower pair of the four-way couplings 15 is asleeve 17, and attached to the posts 11 between the lower pair of theT-couplings 16 is a. sleeve 19.

Each of the posts 11 of the head and foot pieces is provided with alongitudinally extending socket member 20 formed integral with a sleeve19, and the said members 20 project toward each other and are adapted tohave detachably mounted therein the tongues 21 of the side'rail 22whereby the said socket members 20 are connected together. Each of theposts 10 of the head and foot pieces is provided with a longitudinallyextending socket member 23, and the said members 23 project toward eachother and are adapted to receive the tongues 21 carried by the otherside rail 25 whereby said members 23 are connected together. The siderail 25 has projecting outwardly therefrom a pair of eyes 26.

The shiftable section of the bed includes a foot piece and a head piece,the latter being of greater height than the former, but with thisexception, the said foot and head pieces are constructed alike, and thedescription of one will apply to the other. Each of the foot and headpiecesof the shiftable section consists of a post 27 provided with aseries of T-couplings 28 which are arranged in alinement with thefour-way couplings 15 of the posts 10. Connected with each of the posts27 is a series of horizontally disposed rails 29 which extend throughthe four-way couplings l5, and are capable of nesting in the tubularmembers 12, when the bed is closed. The free ends of the rails 29 areprovided with any suitable means to prevent their complete withdrawalfrom the four-way couplings 15. Each of the posts 27 is furthermoreprovided between the lower pair of T-couplings 28 with a sleeve 30.Formed integral with the sleeves 30 are oppositely disposed andlongitudinally extending socket members 31 which are arranged parallelto the rail 25, and which are adapted to receive the tongues 32 carriedby the mattress support 33 which forms an element of the shiftablesection of the bed. The mattress support 33 is also provided with hooks34 which engage in the eyes 26 when the tongues 32 are seated in themembers 31.

' The lowermost four-way couplings carried by the posts 10 are providedwith oppositely disposed longitudinally extending socket members 35 toreceive the tongues 32 of the mattress support 33 when the bed isfolded, and as illustrated in Fig. 1. The mattress support 33 isprovided with a pair of supporting legs 36. When the bed is folded, themattress support is connected to the members 35 and is mounted upon itslegs 36, as well as being positioned below the rails 2225 of thestationary section of the bed. When the shiftable section of the bed isextended to the position shown in Fig. 6, the mattress support 33 hasthe tongues thereof seated in the members 31, and the hooks 34 thereofengage in the eyes 26 whereby the mattress support will be arrangedparallel to the rails 22-25 of the stationary section.

What I claim is An extensible bed comprising a stationary and ashiftable section, said stationary section including head and footpieces provided with horizontally disposed tubular members and furtherincluding rails connecting the head and foot pieces together, saidshiftable section including head and foot pieces provided withhorizontally disposed rails slidable in said tubular members and furtherincluding socket members, and a mattress support detachably engagingwith said socket members and with one of the rails of the stationarysection for maintaining said support parallel to said rail, saidstationary section further provided with socket members for detachablyconnecting thereto, said mattress support when the bed is cl0sed, andsaid mattress support provided with legs for supporting the inner sidethereof when said support is detachably connected to said stationarysection.

In testimony whereof I affix my signature in the presence of twowitnesses.
